crypto: msm: Add basic suspend resume functionality
If ce clock is not disabled in suspend state, memory may be corrupted
and device can not wake up. We add an optional flag "clk_mgmt_sus_res"
for qcrypto driver. This flag indicates if the ce clocks need to be
disabled in suspend function and enabled in resume function of qcrypto
driver. When the flag is set, we disable the clocks that are not disabled
in suspend function and re-enable them again in resume function.
